智利周末遭受地震袭击之后，铜价在周日晚上骤然上涨至七周最高点。
Copper prices rose sharply in electronic screen trading Sunday night and hit a seven-week high after a weekend earthquake rocked Chile.
由于智利是全球最大的产铜国，地震引发的供应量担忧导致铜价上涨。
The boost came from worries about supplies, since Chile is the world's largest copper-producing nation.
分析师称，到目前为止，地震对采矿业的实际影响看来有限，部分是因为8.8级地震发生在智利南部的沿海海域，而许多大型采矿业务均位于北部。
So far, analysts say, the actual impact on mining operations appears limited, particularly since the 8.8-magnitude quake struck in the waters off the southern portion of Chile and many of the major mining operations are in the north.
但有报道称地震至少造成了一些采矿业务被迫中断。而且分析师称，即使矿山遭受的损毁有限，人们也会有其它方面的担忧，例如是否有充足的电力和燃 料，以及至少在近期如何将这些金属运往市场等。
Still, there were reports of at least some disruptions. And even if mines suffer limited damage, analysts said, there are still other worries, such as availability of electricity and fuel, plus transportation of metal to the market, at least in the short term.
Archer Financial Services分析师普莱特(Stephen Platt)说，由于基础设施受损，智利的铜供应将受到干扰，风险溢价目前在市场中得到了体现，公司正对这一预期做出反应。
'We are responding to the prospect that, due to damage to infrastructure, supplies from Chile will be disrupted, and [the market] is putting in a risk premium,' said Stephen Platt, analyst with Archer Financial Services.
在纽约商品交易所(New York Mercantile Exchange) Comex分部，三月铜期货周日晚上涨15.95美分至每磅3.4280美元，涨幅4.9%。拥有最多未平仓持有量的五月合约上涨16.20美分至 3.4460美元，涨幅4.9%。
Sunday evening, nearby March copper was up 15.95 cents, or 4.9%, to $3.4280 a pound on the Comex division of the New York Mercantile Exchange. The May contract, which has the most open positions, was up 16.20 cents, or 4.9%, to $3.4460.
伦敦金属交易所(London Metal Exchange)周一电子交易开市时，铜价上涨5.6%，但不久即开始下跌，证明这是条件反射性上涨。伦敦金属交易所铜的交易价格为每吨7,439美 元，比前一个下午的场外交易价格上涨了3.4%。
London Metal Exchange copper rallied 5.6% at the open of electronic trading Monday, but the move proved to be a knee-jerk reaction, with prices retreating soon after. LME copper traded at $7,439 a ton, up 3.4% on the previous afternoon kerb.
标准银行(Standard Bank)分析师在Comex开市前不久发布的研究报告称，目前地震对铜生产的影响看来有限，但却不容忽视，目前市场前景依然表明铜供应方长期表现不佳。
'The impact on copper production appears to be limited for now but should not be insignificant in a copper market that continues to see a chronic underperforming supply side,' said a research note put out shortly before the Comex open by analysts with Standard Bank.
该报告称，智利占世界铜供应量的约三分之一。
The Standard Bank research note said Chile accounts for about one-third of the world's copper supply.
标准银行称，地震对智利的基础设施毁坏严重，特别是电力供应，致使约17%的铜生产受到影响。智利铜产量的17%相当于全球铜产量的近5%。无 论如何，最初的迹象表明，铜生产受到影响的情况不会持续太久。
'But there was sufficient infrastructure damage to the country -- especially to power supply -- that around 17% of the country's copper production was disrupted,' Standard said. 'Seventeen percent of Chile's copper production equates to almost 5% of world copper production. However, initial indications are that major disruptions to copper production should not last long.'
标准银行称初期报告表明，位于智利首都以北的大型铜矿，包括Escondida、Collahuasi和Chuquicamata等均未受到严 重影响。
Early reports indicate that the large copper mines north of the capital, including Escondida, Collahuasi and Chuquicamata, weren't affected significantly, Standard said.
智利国家铜业公司(Codelco)的El Teniente和Andina两矿被迫关闭，但该公司称预计两矿很快将恢复运营; 后来又宣布El Teniente已恢复运营，但Andina仍然关闭。
Codelco's El Teniente and Andina operations were shut down, but Codelco said it hoped both would be open soon and later announced it was reopening El Teniente; Andina was still closed.
标准银行称，其它受影响的铜矿包括：英美资源集团(Anglo American PLC)的Los Bronces和Anglo公司的El Soldado。
Other operations that were affected, Standard said, were Anglo American PLC's Los Bronces mine and Anglo's El Soldado mine.
标准银行称，至少目前智利的出口大部分应该不受影响。尽管圣安东尼奥（San Antonia）的港口已经关闭，但Antofagasta和Mejillones的港口看来未受太大影响。
For now at least, Standard said, exports from Chile may be 'largely unaffected.' While port activities at San Antonia are closed, the ports of Antofagasta and Mejillones don't appear to have had a major impact.
普莱特说，铜价存在过度上涨的风险。
There is a risk that the rally in copper prices could become 'overdone,' Mr. Platt said.
与周五下跌的收盘价相比，在Comex通过电子交易的五月铜期货的开盘价上涨了约10美分，随后迅速上扬。
May copper opened electronic trading on Comex roughly a dime above Friday's pit close and quickly accelerated to the upside.
